Height in Inches Calculator
Enter your height in any unit and this calculator converts it to inches, then shows the equivalent in every other common measurement: feet and inches, centimeters, meters, yards, and millimeters. Choose whether you are starting from feet and inches (the standard US format), centimeters, or meters. Results update as you type.
How to convert height to inches
The inch is the base unit for height in the United States and the United Kingdom. Converting from other units is straightforward with a fixed conversion factor for each. From feet and inches, multiply the feet by 12 and add the leftover inches: a person who is 5 feet 9 inches tall is 5 x 12 + 9 = 69 inches. From centimeters, divide by 2.54, because there are exactly 2.54 centimeters in one inch, so 175 cm becomes 175 / 2.54 = 68.9 inches. From meters, multiply by 39.3701: 1.75 m x 39.3701 = 68.9 inches. All three routes give the same answer, which this calculator confirms automatically.
How to go from inches back to feet and inches
To convert total inches back to the familiar feet-and-inches format, divide by 12 and keep the quotient and remainder separate. For example, 69 inches divided by 12 gives 5 with a remainder of 9, so 69 inches is exactly 5 feet 9 inches. For a decimal total like 68.5 inches, the whole-number part of 68.5 / 12 is 5 (giving 60 inches from the feet), and the remaining 8.5 inches are written after the feet, producing 5 feet 8.5 inches. Most tape measures show both feet and inches, but medical and sports databases often store heights only as total inches, making this conversion frequently needed.
Centimeters versus inches for height
The United States, Liberia, and Myanmar are the only countries that commonly express human height in feet and inches rather than centimeters. The rest of the world uses the metric system, so international height databases, medical research, and clothing size charts often quote height in centimeters or meters. The exact conversion is 1 inch = 2.54 cm, making it a simple multiplication or division. Because 2.54 is not a round number, a 5-foot-10-inch (70-inch) person is 177.8 cm, not a round 178, which is why rounding conventions matter when comparing heights across different systems.
Why height units matter in everyday life
Height conversions come up in several practical settings. Medical records in the US typically record height in inches, while pharmaceutical dosing guidelines and global research papers use centimeters. Clothing and shoe size charts in European brands list height in centimeters. Passport and visa application forms may ask for height in either system depending on the country. Online height comparison tools, door frame clearances in construction, and sports statistics all use different conventions. Knowing how to move between units quickly avoids the rounding errors that crop up when people eyeball a conversion rather than calculating it exactly.

Frequently asked questions
How many inches are in 5 feet?
5 feet equals exactly 60 inches. The conversion is 1 foot = 12 inches, so 5 x 12 = 60. Common heights in this range: 5'0" = 60 in, 5'6" = 66 in, 5'9" = 69 in.
How do I convert centimeters to feet and inches?
First divide centimeters by 2.54 to get total inches, then divide total inches by 12. The whole-number part of the result is feet, and the remainder is inches. For example, 170 cm / 2.54 = 66.93 inches, which is 5 feet 6.93 inches (or about 5'7").
How tall is 175 cm in feet and inches?
175 cm divided by 2.54 equals 68.90 inches. Dividing 68.90 by 12 gives 5 with a remainder of 8.90, so 175 cm is 5 feet 8.9 inches, commonly rounded to 5'9".
What is the average height in inches?
The global average height for adult men is approximately 69 inches (5'9" / 175 cm), and for adult women approximately 63.8 inches (5'3.8" / 162 cm). Averages vary by country: men in the Netherlands average about 72.8 inches (185 cm), while global averages are pulled lower by South and Southeast Asian populations where average male height is closer to 65 to 66 inches.
How do I convert my height from a decimal number of inches to feet and inches?
Divide the total inches by 12 using integer division to get the feet, then subtract (feet x 12) from the total to get the remaining inches. Example: 67.5 inches / 12 = 5 remainder 7.5, so 67.5 inches = 5 feet 7.5 inches.
Is 6 feet tall in inches 72 inches?
Yes. Exactly. 6 x 12 = 72. Six feet is 72 inches, 182.88 centimeters, or approximately 1.829 meters.
